Pen Arm Calibration:
To check and/or adjust the recording pen(s) calibration to the outer most temperature
graduation of the chart, press and hold the "change chart" button (#3) until the pen
begins to move off of the chart. Once the pen(s) has moved off of the chart, again press
and hold the "change chart" button (#3) until the pen begins to move back onto the chart.
The pen should briefly stop at the outer most temperature graduation of the chart before
continuing onto the chart to begin recording. If the pen does not stop exactly at this
location on the chart, it can be adjusted or "calibrated" by using the left (#1) or right (#2)
arrow buttons.
When the pen moves back onto the chart and briefly stops, you will have approximately
five seconds in which to adjust the pen’s position using the left and right arrow buttons
of Figure 3.
On multiple pen recorders, each pen will move (one at-a-time) onto the chart briefly
stopping at the outer most temperature graduation of the chart at which time the pen’s
position can be adjusted by using the left (#1) or right (#2) arrow buttons. When the time
to adjust the position of the first pen has expired, the second pen will move onto the chart
briefly stopping at the outer most temperature graduation of the chart at which time the
second pen’s position may be adjusted.
Each time the chart paper or fiber tip pen cartridge is changed, you should make sure
that each pen stops at the outer most temperature graduation of the chart paper.
Otherwise, this pen offset will cause the unit to record an incorrect temperature on the
chart.
Recorder Calibration:
If a calibration adjustment is required for a single pen recorder, use the left (#1) and
right (#2) arrow push buttons on the recorder to calibrate (or move) the pen’s position
on the chart to correspond to the temperature of the solution. The arrow buttons must
be held for approximately five seconds before the pen will begin to move.
For two pen recorders, you must first select the pen that you wish to calibrate. This is
done by pressing the left (#1) arrow button to select the red pen or the right (#2) arrow
button to select the blue pen. The arrow button must be held down until the green LED
light goes out. After the green LED light goes out, follow the instructions in step #3
above.
